MATI-IEYV DELKER, OF DETROIT, MICHIGAN.

BUNG.

SPECIFICATION forming part of Letters Patent No. 411,239, dated September 17, 1889.

Application filed December 31, 1888. Serial No. 295,107- (No model.)

To all whom it may concern:

Be it known that I, MATHEW DELKEE, a citizen of the United States, residing at Detroit, in the county of \Vayne and State of Michigan, have invented a new and useful Improvement in Bungs for Beer and Liquor Gasks, of which the following is a specification.

My invention has for its object an improved means of closing and keeping temporarily closed the opening through the metallic bung commonly inserted in the spigot-hole of a beer or liquor cask. It is usual to close the lower end of the aperture through the bung, when it is desired to insert it in the spigot-hole, by a cork, and after the bung is driven to place the cork is forced out into the cask by means of the tube that forms the stem of the pump or faucet, which stem is inserted through the bung.

My improvement is shown in the drawings, of which Figure 1 shows a section of the bung and of the stopper used to close the lower end and of the supporting-rod by which the stopper is held in place, and shows also the end of the tube or stem of the faucet and the means by which thatis locked to the supporting-rod; and Fig. 2 shows a section of the bung with the pump-stem in place in the aperture through the hung, with the stopper driven out and held at the end of the pumpstein.

A represents the hung, which has at its lower end an annular recess-seat B, into which the circular plate or stopper 0 fits closely. To the upper side of the plate 0 is attached a rod D, jointed at d, the relative lengths of the portions of the jointed rod being such that the length from G to (Z will bring the joint cl just below the top of the bung when the stopper G is pulled up snugly into the seat B, and the short portion from d to O is suffieient to reach from the center of the bung to the outside of the same, and in order to hold the stopper 0 in the seat B while the bung is be ing driven into the spigot-hole the short arm (Z O of the jointed rod is turned down into a dent E cut through the wall of the bung. The dent E, is sufficiently wide to permit the end (1 O of the rod to be pressed down into it, and it is sufficiently narrow to hold the rod when pressed down into it by frictional contact between its sides and the rod, so that the weight of the stopper 0 will not pull the rod D d 0 straight. A very small amount of frictional resistance accomplishes this result. This permits the use of a hammer in driving the bung to place without danger of injury to the supporting-rod.

On the end of the short arm of the jointed rod is a bead or knob O. In the lower end of the pump-stem F is an internal screw-thread adapted to receive the externally-threaded nipple G. The opening through the nipple G is constricted at its lower part, and has coinmunicating a slot S, out through the wall of the nipple. The lower part of the slot- S corresponds in width with the diameter of the 0011- tricted portion of the opening through the nipple and is of a width sufficient to permit the supporting-rod heretofore described to pass sidewise through it into the opening through the nipple. The upper part of the slot is enlarged sufficiently to permit the passage of the bead or knob 0 through it into the interior opening through the nipple. A corresponding slot T is cut through the walls of the pump-stem and is arranged to register with the slot S in the nipple G.

A tight connection between the interior of the bung and the exterior of the pump-stein is produced by means of the packing-ring H and the screw-pressure ring I, which are of the usual form for making such connection.

A free flow of the liquid from the cask to the interior of the pump-stein is permitted through the perforations P P P, made near the bottom of the pu1np-ste1n through its walls or through the nipple. To operate my invention the circular plate 0 is placed in the seat B, with its supporting-rod extending through the bung, and is locked in position by turning down the jointed portion of the supporting-rod into the dent E. The bung is then driven to place, the jointed portion of the supporting-rod turned upright, and the head on its upper end inserted through the enlarged portion of the slots S Tinto the nipple, which is in place in the lower end of the pump-stem. A quarter-turn of the nipple in the pump stem will now look the supportingrod in a position such that it cannot escape,

but will readily pass up in the interior of the stem and allow the stem to come down against the stopper 0.

Having thus described my invention, WhatI claim as novel, and desire to have secured to me by Letters Patent, is

1. I11 combinationwith a bung having an opening therethrough, a stopper arranged to close the opening at its lower end, said stopper having a supporting-rod projecting from its upper surface and arranged to extend upward through the bung and to lock the stopper thereto by frictional cont-act between the upper end of said rod and a dent cut through the Walls of the bung, substantially as and for the purposes described.

2. The combination of a hung having an opening through it, a stopper arranged to close the lower end of the opening, a supportingrod extending upward from the stopper and having a knob at its upper extremity, and the described slotted nipple connected to the pump-stem and arranged to receive and hold the said supporting-rod by means of the knob, substantially as and for the purpose 25 described.
